A tube in vertical plane is shown in figure. It is filled with a liquid of density `rho` and its end `B` is closed. Then the force exerted by the fluid on the tube at end `B` will be : [Neglect atmospheric pressure and assume the radius of the tube to be negligible in comparison to `l`]

A liquid of density rho comes out with a velocity v from a horizontal tube of area of cross-section A. The reaction force exerted by the liquid on the tube is F :

Figure shows as thin tube open at one end rotating with constant angular speed omega . The other end of the tube has a small opening. Tube contains a fluid of density rho which effuses with speed u relative to the tube. Let rho_(A) be the pressure at the point in the tube just behind the opening. Assume the atmospheric pressure to be p_(0) and pick correct option(s) for the instant when h=l/2

Water flows out of a big tank along a horizontal tube Ab of length L and radius R and bends at right angle at the other end as shown in the figure. Find moment of force exerted by water on the tube about the end A (Assume that the radius of the tube is small )
